ATIE360, 380, 3900 Sport, ATV Pool Cleaners Wheel Ball Bearing 9-100-1108 Replacement for Polaris 360, 380, 3900 Sport, ATV Pool Cleaners Part No. 9-100-1108 (8 Pack)

My polaris 380 stopped moving and I found a completely shot bearing on the left wheel. These are not Polaris parts but for 1/4 of the cost I decided to give them a shot. The first photo is what remained of my polaris bearing, basically nothing. It was pretty straightforward installation. Remove the remnants of the old bearing and pop the new one on the axle. It was a perfect fit. The polaris is running like new just in time for the cleanup of Hurricane Michael! On a side note, I only replaced the one bad bearing but this 8 pack is enough to replace all the bearings in the pool cleaner. You would have to spend 48 bucks and buy 2 four packs of the actual Polaris part number. I will update this if the bearings do not last a sufficient time.

I'd inherited my Polaris 360 from the prior house owner 19 years ago and didn't have to do repairs on it (including bearings) for years. But when the bearings eventually failed, I looked for reasonably priced replacements. These seemed pretty good (although really hard to get on the metal axle). But none of them have held up. Probably get 12-18 months of use before they disintegrate. And replacing bearings isn't a fun thing to do regularly. Is it worth paying 6X the price... maybe. Assuming the polaris bearings made these days last as long as the original ones did...

Good price, but questionable quality. They looked good when installed and held up great for a bit shy of 2 years. There is a blue plastic retainer that holds the ball bearings in the track and they have all separated from the housing allowing the ball bearings to float out loose inside the Polaris. It may have happened for a while but I didn't notice until the cleaner stopped moving and I found the belt came off the wheel gear. Need to replace the 2 double side wheels too since one side of both gears attached to the wheels are worn out. Suspect these loose bearings contributed to the wear since they failed to hold the gears snugly in place. But still, they are so much cheaper than in the local store.

Good price, but questionable quality. They looked good when I first installed, and they held up great for a while. But after about 18 months they all failed simultaneously. There is a blue plastic retainer that holds the ball bearings in the track and they have all separated from the housing allowing the ball bearings to float out loose inside the Polaris. Luckily most of them were sucked into the bag but what a pain fishing tiny ball bearings from the bottom of the pool!

These do not work. They are tight and rough and I wasted my money. These would not allow my wheels to spin freely and I ended up having to trash them all. Really disappointed. Per my pool guy, buy the brand name Polaris replacements. Yes they are $12 each, but they work. I put the real ones in and my Polaris works just fine now.

Changed bearings while doing a belt change on my 360. Good thing I ordered these because the originals were mostly shot. Bearings appear to be of better quality than what were installed in my Polaris, but those could have been 2nd rebuild as I inherited this sweep with the new place. Anyway, real pleased with the bearings. Install was mostly easy with help from Utube video 360 & 380 belt replacement as a guide to disassembly. Product was packed nicely and shipping as promised.

Installed these at the beginning of the 2019 summer pool season. Some where a bit tight but was able to install of them.Recently the Polaris became very sluggish. Inspected the bearings and they seem to be holding up well. The issue was unrelated to the bearings. FYI for other owners, the jet inside the unit powering the paddle wheel and gears can get clogged and symptoms (sluggish movement) is identical to worn bearings. Paperclip or thin wire is all you need to clear that jet and the jets that shoot up into the bag. So shine a flashlight into that jet to make sure it is open first before you start pulling apart the wheels to check the bearings.

Fit all the shafts in my Polaris 360. Bearings slide on pretty tight on the shaft and a little loose in the housing/body but still worked. Does not fit the drive train gear bearing. Must order the drive train gears/bearing package separate.
